CORNER CONNECTION FOR METAL FRAMES Filed Aug. 5 1929 Patented Oct. 13, I931 UNITED- STATES CORNER CONNECTIGN -Application filed August 5,

My invention relates to buildingconstruction and more particularly to corner connections for metal opening construction.

In the use of metal framing for openings in which two vertical and horizontal members are utilized, considerable difi'iculty has been experienced in constructing a suitable corner connection for the vertical and horizontal members. i i I I a An object of my invention is to provide asimple and economical securing means for two intersecting metal frame members which is simply manufactured and readilyinstalled on the j oh by unskilled labor.

. A further objectof my invention is to provide a suitable corner connection: for inter- 'secting metalframes of a simple construction yet insuring absolute rigidity and avoiding the possibility of the frames thereafter war'p- V ing or separating by reason of internal stresses orblows directedthere'against. A further object of my invention is to provide a metal frame construction having a cor: ner connection'which absolutely insures freedom from movement eithervertically horizontally or laterally. v

My invention will be more readily understood by reference to the accompanying drawings in which v Fig. 1 is a plan viewof areorner' connection constructed in accordance with my invention;

Fig. 2 is a rear elevation thereof; I I Fig. 3 is a side elevation thereof; and i Fig, 4 is a vertical sectional view on line 4;--tofFig. 1. I I

Byreference 'to the drawings it will be seen that I have illustrated two intersecting metal. opening frames A and B having the rebent plaster defining terminals 10,.11, 12, and 13, the plaster terminals :10 and 11 being suitably welded to the horizontalframe metal B and the plaster terminals 12 and 13 being suitably welded to the vertical members A. The webs of the respective frame members are suitably and 15. c I I V 1 Between the flanges of the vertical frame 7 member A Ihave welded the channel shaped member 16, having apertures therein adapted to receive bolts 17 and 18 passing thereber B fitted over the vertical member A; so F that the tongues 21. and, '22 'will' project bent to provide the door stops 14 I mean PATENT OFFICE" CHICAGO, ILLINOIS r0 METAL FRAMES 1929.

through and the web of the member B'is provided near its outer extremity with suit- I able registering apertures for the reception of the bolts 17 and 18 having cooperating 7 nuts 19, 20. I

On the 'verticalframes, adj acentto the door stop 15, I provide the tongues 21, 22 which project upward from the web and are adapted to be inserted through registering slots in the web of the horizontal member B.

, i at It will benoted that I have construct-ed the vertical frame members in such a- Way that'a substantialportionis cut out of the metal constituting thedoor stop 15 at the v upper; extremity thereof for the reception of ighedoor stop 14 of the horizontal frame memer. H

In installation the vertical members are temporarily set up and the horizontal memthrough the apertures in the horizontal mem her; The tongues are then readily'bent'down into contact with the web of theframe, and a preliminarysetting is effected. Thebolts 17 and 18 are then inserted from the back side of the vertical members, through the registeringapertures in the member 15 and the web B and the nuts 19 and 20 are screwed down from the inside of the horizontal chan- 'nel shaped member B to effect a positiveand final rigid connection at the corners.

It is obvious that I have a metal frame opening having a corner connection of the utmost simplicity and insuring the absence of any movement laterally by reason of the tongues 21 and 22 firmly engaging the web of the cross member B; the bolts 17, 18 prevent upward movement of the cross member B, and the cut out portion "of the vertical door stop prevents any horizontal movement of the cross: member. The vertical and cross members are thus r gidly and permanently secured and all possibility of movement in anydirection isthus eliminated. t

WhileI'have shown and claimed anoninstruction infwhichthe head frame overlies the ends of the said frames it will be understood that this construction may bereversed I herein disclosed a without invention. That is, the same interlocking connection may be made Where the side frames overlie the ends of the head frame.

Obviously numerous variations and modifications may be made in the construction herein disclosed and I do not wish to be limited except as indicated in the appended claims.

I claim:

1. A corner connection for intersecting ver tical and horizontal frame members, comprising a pair of vertically disposed channel shaped metal frame members and a horizontally disposed channed shaped member, said horizontal member having a plurality of spaced slots in the web thereof near the outer extremities of said member, a pair of upwardly extend. g tongues on each of said vertically disposed members, said tongues being adapted to enter said slots and to be bent over, and threaded means cooperating between said intersecting members near the outer extremities thereof to rigidly secure the same.

2. In combination a pair of vertically disposed frame members, rebent aster defining strips on said frame members extending longitudinally thereof, a horizontally disposed channel. shaped head piece, said. head iece having a plurality of spaced slots in the web thereof near the outer extremities, a pair of rebent plaster defining memberssecured to the flanges of said head member and extendin substantially the length thereof, a pair of upwardly extending tongues formed from the metal in the Web of said vertical members. said tongues being adapted to be received in the slots in said horizontal member, and threaded means cooperating between said horizontal and vertical members, to firmly join the same together.

3. Means for securing intersecting metal frame members, comprising in combination, verti *al and horizontal channel. shaped frame members, said horizontal member having a slot near each extremity thereof, an upwardly extending tongue formed out of the metal of the web of said vertically disposed memers, said tongues being adapted to be received w'thin the slots in said horizontal member, an apertured metal strip secured to the flanges of each of said vertically disposed memoers near the upper extremity thereof, and threaded means cooperating between said strip and the web of said horizontal member for securely joining the same.

4:. Means for securing intersecting metal frame members against lateral and vertical separation, comprising in combination vertical and horizontal metal frame members, said horizontal member having a plurality of adjacent slots near the extremities thereof, a plurality of tongues extending upwardly from the upper extremity of the vertical frame members and adapted to be inserted into said slots, a door stop formed out of the metal of said vertical and horizontal members, an apertured metal strip secured to one face of said vertically disposed members near the upper extremity thereof, and threaded means cooperating between said strip and said horizontal member for securely joining the same.
